I wouldn't go as far as right. A real expert will be able to give a much deeper dive as to what is likely in that licence agreement and probably pick me up on various bits of "fluff" in my posts. Generally in licensing, specifically software, anything made using a technology which is already licensed carries the same license on which it was based, obviously there are exceptions as that kind of license would be useless with something like visual studio, anyway we were doing a quantum computing project (for a quantum computing compiler) for which I was asked to audit code only a few weeks ago and we ran into exactly this. Really interesting and the guy that's looking to protect his work incredibly intelligent.
I've still got qubits on the brain since that work and I still don't fully understand it even after asking a million times to "explain that again". Luckily I don't need to understand it fully my job at that point is to trawl through code looking for things like calls and integration of current and known quantum code. You would be surprised by the amount of licensed quantum code on github.
